Description

The LMG3626EVM-074 evaluation module (EVM) demonstrates high-efficiency and high-density for a 65-W USB Type-C® power delivery (PD) off-line adapter using the LMG3626 integrated GaN FET with current-sense emulation. The input supports a universal 90 Vac to 265 Vac and the single output can be set to 5 V, 9 V and 15 V all at 3-A maximum and 20 V at 3.25-A maximum, which can be adjusted with the USB PD interface controller. High frequency operation up to 200-kHz nominal enables small solution size while the multi-mode operation maintains high efficiency. Synchronous rectification is used on the output to increase efficiency.

Features

  • 93-94% Efficiency under full-load operation under entire input voltage range
  • 28W/in3 Power density enabled by 180-kHz maximum switching frequency
  • Current sense emulation greatly reduces power losses associated with traditional current sensing circuitry
  • Integration of GaN, driver, OCP, and OTP simplifies design, reduces BOM count, and increases system robustness
  • USB-C output enables full system-level evaluation for end-equipments like adapters, notebook chargers, USB wall outlets

Typical applications

  • notebook computers, tablet computers, TV, and set-top box
  • USB-C PD Power Adapters, AC-to-DC or DC-to-DC auxiliary power supplies, USB-C PPS Power Adapters
